This edition of the ASEAN+3 Bond Market Guide series focuses on updates in the Republic of Korea's (ROK) market since the publication of the previous guide for the ROK in 2018. It outlines strategies by policymakers and regulators to make the market more accessible for international investors. It shows how the ROK has removed a key hurdle to market entry, changed withholding tax exemptions, and increased sustainable finance issuance. It explains how the combination of policy changes and the likely inclusion of Korean government bonds in international indices could see the market's healthy grow continue.
